If applicant chooses to divide a file into multiple parts using the multi-doc feature, each part is counted as one file. The need to submit unusually large sequence listings and/or numerous electronic files may prevent applicant from making a complete international application (PCT) filing in a single EFS-Web submission. Registered EFS-Web users may file part of the international application (PCT) to obtain the international application (PCT) number and the confirmation number, and then file the remainder of the international application (PCT) on the same day as one or more follow-on submissions using EFS-Web, in order to secure the same filing date for all parts of the international application (PCT).
